I was shifting at 6500 and crossing at 6200 I felt I was not using all of my motor.



At the same Et and MPH that your running now, the 5.13,s should put you close to 7000 RPM,s in the 1/8th. With a faster MPH, that you want to run to beat your buddy, even more RPM,s I just think the 5.13,s were to big of a jump for what your trying to do.

At your level of performance, I agree you wont see a Whole lot of performance gain from the Comp increase, but I think it may be just enough.

As asked, have you tried different shift points then 6500? Or has that been the best for your combo?
